"Industrial Application Field" The present invention relates to a sterilizing water purifying agent for drinking water that clarifies and sterilizes water to be treated to make it into drinking water in the field or in an environment where there is a shortage of drinking water. "Prior art and its problems" As reported in the newspapers recently, in Africa, in addition to the problem of food shortage,
Drinking water shortage has become a serious problem. As a result, they drink rainwater and river water to stave off hunger, but this has led to outbreaks of diseases and infectious diseases caused by pathogenic bacteria in the water. In order to cope with such a situation, there is a strong demand for a potable sterilizing water purifying agent that can provide life-saving drinking water on an urgent and temporary basis. In addition, if rainwater or river water can be immediately purified and made into drinking water, it would be convenient for outdoor activities such as camping, since there would be no need to bring along water bottles, which are heavy and have a limit on the amount you can carry. be. However, in order to sterilize rainwater, etc., it is not enough to simply use a sterilizing agent; the sterilizing agent must be harmless to the human body, but most conventional sterilizing agents are also harmful to the human body. It was hot. Conventionally, as a method for sterilizing and purifying drinking water, for example, as described in Japanese Patent Publication No. 52-40148, fluoride is added to raw water, electricity is applied to generate fluoride ions by ionization, and the generated fluoride ions are There is a known method for purifying water by sterilizing bacteria contained in the water. However, in order to make a portable water purifier using this method, it is necessary to fill it with self-soluble electrodes in the form of lumps or particles that can conduct a galvanic current as a portable energizing means, which is extremely costly. Therefore, as mentioned above, it could not be used as a disinfectant and water purifier for drinking purposes, which was supplied in large quantities to Africa for aid purposes. ``Means for Solving the Problems'' The present inventors focused on this point and conducted intensive research, and found that it can be synthesized by an industrially extremely inexpensive method, and has excellent turbidity removal and sterilization abilities. , we have successfully developed a drinking water disinfectant that is harmless to the human body.
We have arrived at the present invention. That is, the present invention provides various metal salts and non-metal salts obtained by dissolving vermiculite in which mica-based minerals have weathered or soil in which this vermiculite has further weathered, in an aqueous solution of an inorganic acid such as sulfuric acid or hydrochloric acid. This is a sterilizing and water purifying agent for drinking, characterized by comprising an acidic additive as a main component. To prepare the sterilizing water purifying agent for drinking according to the present invention, for example, a 25% aqueous sulfuric acid solution is added to vermiculite, which is weathered mica-based minerals, at a weight ratio of vermiculite:sulfuric acid aqueous solution of 4:3 to 4. Add the mixture and leave it for several days with occasional stirring, or heat it to 100°C and leave it for several days while stirring. In this way, Si, Al, Mg, Fe in the raw materials,
Elements and oxides such as K and Na are eluted into the sulfuric acid aqueous solution, and the above metal and nonmetal sulfates, oxides, double salts, and complex salts are produced. Furthermore, in addition to the above, Li, Zr, V, Ni, Co, P, Ba, S, which are contained in the raw materials as elements or oxides, although in trace amounts.
Although sulfates such as sulfates are also produced, there are no harmful heavy metals. The aqueous solution thus obtained is used as it is or after being concentrated or diluted as a sterilizing water purifying agent for drinking. On the other hand, in order to purify untreated water such as rainwater or river water to the point where it is drinkable, at least the following treatments must be performed. Garbage filtration Removal of suspended solids (SS) Removal of soluble organic materials This is general plant or animal organic matter that has decayed and is dissolved in the control water, including BOD materials, COD materials, and normal This is called hexane extract. In other words, these include carbohydrates such as saccharides and organic acids that have become soluble in water due to decay of organic substances, amino acids that are proteins or their variants, and fatty acids that are fats and oils and their variants. Sterilization The vast variety of bacteria that exist in nature naturally exist and survive in the control water, so they must be sterilized as much as possible. When the sterilizing water purifying agent of the present invention is added to untreated water, it immediately reacts with organic matter in the water, decomposing it while generating carbon dioxide gas, changing the organic matter decomposition products to water-insoluble properties, precipitating, and coagulating at the same time. urge It has also been demonstrated that this reaction simultaneously aggregates visible suspended solids (SS) and that the reaction has a strong sterilizing effect.
The flocs separated and aggregated in this way are
It can be separated using filter paper. As described above, by adding the sterilizing water purifying agent of the present invention, removal of soluble organic substances and sterilization can be achieved at the same time. If there is a means to filter out aggregates and insoluble matter, the treated water can be purified into drinking water. Therefore, if there is a container in which a sterilization water purification chamber and a filtration chamber are provided separately or integrally, treated water can be purified into drinking water. The amount of sterilizing water purifier added to the water to be treated varies depending on the degree of contamination of the water to be treated, but generally it is 1/10000 to 1/5000 (100 to 200 ppm) of the water to be treated.
It is enough. Of course, no harmful effect will occur if the amount added is greater than this, but excess amounts will lower the pH, so it is best to neutralize it with lime water or diluted caustic soda solution. When adding 100 to 200 ppm, the pH is also 6.
~7, which is almost neutral, but to ideally adjust the pH to 7, it is desirable to neutralize it, and neutralization also increases the coagulation effect. Furthermore, depending on the water to be treated, there may be trace amounts of ionized substances. Examples of such ions include cations such as ammonia, calcium, and manganese, as well as chlorine, fluorine, nitric acid, and nitrous acid. In this case, in addition to the sterilizing water purification means and filtration means, an ionized substance removal means is required. For example, an activated carbon filtration layer may be provided to remove anions, and a vermiion filtration layer may be provided to remove cations. Vermiion is a strong inorganic cation exchanger obtained by inorganic chemical treatment of raw vermiculite from South Africa. The exchange capacity of vermi ions is, for example, for counter-ammonium ions, up to approximately
It has 2000meq (milliequivalent). It is of course possible to use other known materials as ionized substance removal means, such as ion exchange resins. Furthermore, some of the water to be treated is slightly colored or emits a slight odor, and in this case, decolorizing and deodorizing means are required. As such, an activated carbon filtration layer may be provided. By using the sterilizing water purifier of the present invention, a portable water purifier can be easily obtained. That is, this water purifier only needs to have a chamber for mixing untreated water and the sterilizing water purifying agent of the present invention and a chamber for filtering. Therefore, if the untreated water and the sterilizing water purifying agent are mixed in separate containers, the water purifier only needs to have a filtration chamber. The filtration chamber may be filled with only filter paper, but since this may cause clogging and slow down the filtration rate, it is preferable to provide a suitable filler layer on top of the filter paper. As such a filler, any filler used for this purpose, such as activated carbon, vermiion, silica, alumina, zeolite, acid shiraki, bentonite, kaolin, and rice hull smoked charcoal, can be used. A suitable example of a filtration chamber is
A chamber for a mixture of activated carbon and vermi ions, a chamber for vermi ions, and a chamber for activated carbon are provided sequentially from the bottom, and filtration chambers in which filter paper is inserted are provided at the upper and lower ends. All fillers in the filtration chamber are preferably wrapped in non-perishable non-woven rayon fabric so that they can be easily replaced when their effectiveness diminishes. Using such a filtration chamber,
Most treated water is purified to almost ideal conditions. The purified water may be received by placing a cup or the like below, or a chamber for receiving the water may be connected to the lower end of the filtration chamber. The chamber for mixing the water to be treated and the sterilizing water purifying agent of the present invention may be a separate container, or may be connected to the upper end of the filtration chamber. In that case, this mixing chamber will not flow down to the lower filtration during the mixing process, but
After mixing, it is preferable to open the opening using a known method so that the mixture flows down into the filtration chamber below. The sterilizing water purifying agent of the present invention can purify fresh water from ponds, swamps, lakes, etc., as well as rainwater and street water, and make it available for drinking. However, toxic wastewater such as industrial wastewater, highly polluted livestock waste water, etc. are not subject to control. "Examples" Next, the present invention will be further explained with reference to Examples, but the present invention is not limited to these Examples. Example 1 500 c.c. of rainwater containing E. coli (approximately 500 bacteria/cc)
To this, 0.5 ml of the water purifying agent of the present invention was added as a 25% aqueous sulfuric acid extract, stirred, and then filtered through filter paper. When the filtrate was sampled and tested for E. coli, the number of E. coli was reduced to less than 13 cells/cc.
As a result of conducting an E. coli test on the filtered insoluble matter, no E. coli was detected. Example 2 0.1% by volume of 25% sulfuric acid aqueous extract was added to river water containing Escherichia coli and organic matter, neutralized with CaO, filtered through a vermiion layer, and the filtrate was sampled for testing. Ta. The results were as shown in the table below. As a result of conducting an E. coli test on the filtered insoluble matter, no E. coli was detected.
